Harvest Dragons are a large, flightless breed most often found in heavily forested mountains. Normally shy, these omnivorous dragons keep to themselves in remote regions, but in the fall they descend from their high territory to search for food—and lots of it. During the autumn months, harvest dragons will eat whatever they can find, from large and small animals to nuts and fruit. In the winter they retreat into large caves and hibernate until spring, living off the fat they have built up.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Autumnleaf is a Harvest dragon with a serious sweet tooth. Hunting isn't a problem for him due to his comparatively large size, yet his diet consists mainly of whatever sweet fruits he can find. Although he is usually a peaceful and cooperative dragon, the moment he sees another dragon with fruit he will try to take it from them, and even resorts to starting fights to get it. However, Autumnleaf is a poor fighter and so usually loses these battles.
